Constructor & Destructor Documentation

Perlin()

Raytracer::Utils::Perlin::Perlin

(

)

Construct a new Perlin object.

This function constructs a new Perlin object. The Perlin object is a Perlin noise generator. The Perlin noise is a type of gradient noise.

Returns

A new Perlin object.

~Perlin()

Raytracer::Utils::Perlin::~Perlin

(

)

Destroy the Perlin object.

This function destroys the Perlin object.

double Raytracer::Utils::Perlin::noise

(

const Utils::Point3 &

point

)

const

Get the noise value at the given point.

This function returns the noise value at the given point.

Parameters

point

Returns

The noise value.

perlinGeneratePerm()

int * Raytracer::Utils::Perlin::perlinGeneratePerm ( )

static

Generate the permutation table.

This function generates the permutation table.

Returns

The permutation table.

perlinInterp()

double Raytracer::Utils::Perlin::perlinInterp ( const Utils::Vec3 c[2][2][2], double u, double v, double w )

static

Interpolate the noise value.

This function interpolates the noise value.

Parameters
